Description

Lighting module and lighting assembly comprising such a lighting module

The present invention relates to a lighting module and a lighting assembly comprising such a lighting module.

The field of application of the invention is that of lighting means, in particular portable or wireless, designed to be implemented in an industrial or mining context, in the context of sports activity, or for use domesticated.

There is known a so-called "frontal" portable lamp system, which can be fixed on the front of a user so as to illuminate an area oriented in the direction of his gaze. The known system sometimes includes a lighting module with light-emitting diodes, and which is provided with a reserve of energy for supplying these diodes, for example a battery or a battery. The known lighting module can be switched from a switched off mode to a user-switched mode, for example by means of a switch whose lighting module is equipped. In the on mode, the lighting module consumes energy from its energy reserve, so that it is necessary to recharge or even replace this reserve of energy regularly. To facilitate this operation, the known headlamps generally comprise an access opening to the energy reserve which is provided in the lighting module, and through which the user can extract the energy reserve in order to replace it with a full energy reserve, or recharge the energy reserve, before replacing it in the lighting module.

The known system also includes a harness attachment of the lighting module to the user's forehead that can be adjusted according to the morphology of the user. In some cases, the lighting module can be separated from the attachment means to facilitate the extraction of the energy reserve by the user.

The known headlamp system allows the user to work or move in a low-light area while keeping their hands free and without the need for an external plug-in power source. Nevertheless, the known system generally has a relatively low autonomy, insofar as the weight and bulk of the energy reserve must be limited to guarantee the portable and manageable nature of the system. Similarly, for the purpose of saving the energy reserve, a lamp of low luminous intensity is generally chosen, and which may be insufficient depending on the use of this headlamp system.

Furthermore, it may be difficult to separate or reattach the lighting module with the attachment means when the latter is in place on the user's head, so that in use , the user can hardly switch from a manual handling mode to a front-end mode of the lighting module.

Finally, the known lighting module is not suitable for use dissociated from its attachment means, insofar as it is small and a shape making it difficult to grip.

Accordingly, the object of the invention is to remedy the various disadvantages mentioned above and to propose a new lighting module, which, while being particularly light and easy to transport, has a particularly high autonomy, presents a Illuminance power that can be adapted to the situation and is easy to recharge.

Figures 1 to 3 illustrate a lighting module 1 which allows to illuminate an object placed in the vicinity, or an area of the near space. The lighting module 1 is portable, that is to say it is of moderate size and can provide light without being connected to a power source such as a power outlet. The lighting module 1 comprises a housing 7, a lighting stage 3, a main battery 5 and a primary terminal 13. For example, the height H1 of the lighting module 1 is comprised in 1 and 10 cm , while its maximum horizontal dimension is between 4 and 12 cm.

The housing 7 defines a main axis X1. The housing 7 has a general shape of a puck, and in particular has a generally cylindrical shape which is coaxial with the main axis X1. In the example shown in Figures 1 to 4, the cylindrical shape is substantially hexagonal base with rounded corners. Other basic forms can be envisaged, for example discoid or polygonal.

In what follows, the terms "up", "down", "upper" and "lower" are used, which are defined for the lighting module 1, when it is oriented according to FIG. that is, with its main vertical axis X1 substantially vertical, the lighting stage 3 towards the "up", the housing 7 at a median level, and the primary termination 13 towards the "bottom".

The casing 7 comprises an inner part or armature 47 which is preferably made of a rigid plastic material of the polypropylene type. The inner part 47 forms an annular wall 51 coaxial with the main axis X1. The annular wall 51 extends parallel to and away from the main axis X1 so as to surround the latter at a distance. The annular wall 51 forms six planar portions 53, 55 distributed around the main axis X1 and each having a rectangular shape parallel or orthoradial to the main axis X1. The planar portions 53, 55 are connected to one another by a filleted portion 57 which protrudes, so as to form a continuous annular wall. The inner part 47 also comprises a bottom wall 59 extending orthogonally with the axis X1, inside the annular wall 51. The latter extends between a lower edge 61 and an upper edge 63, the bottom wall 59 closing the annular wall 51 at the lower edge 61.

The inner part 47 also comprises three slots 17, 19 and 21 which are arranged in the annular wall 51, at three of the flat portions 55. The slots 17, 19 and 21 are regularly distributed around the main axis X1 and are formed recessed inwardly of the inner part 47, that is to say in the direction of the main axis X1, from the lower edge 61. Thus, a flat portion 53, 55 out of two receives one slots 17, 19 and 21.

Each slot 17, 19 and 21 is delimited by two primary anti-rotation edges 1523 which are interconnected by a primary stop edge 1519, the latter forming the upper wall of the slot to form a "U". The primary anti-rotation edges 1523 extend parallel to the main axis X1, while the primary abutment edge 1519 extends perpendicularly to this axis. The crenellations 17, 19 and 21 thus have a generally rectangular shape. Furthermore, the slots 17, 19 and 21 each form a recessed surface 1527 which is parallel to the plane portion face 55 in which the slot concerned is formed, and which is withdrawn with respect to the latter in the direction of the axis X1 . Thus, the recessed surface 1527 is delimited by the primary stop edge 1519 and the two primary anti-rotation edges 1523.

The housing 7 also comprises an outer part 49, or skin, which is made of a softer material and / or with a coefficient of adhesion higher than the inner part 47, and which is for example made of elastomer, which makes it advantageously confers a non-slip character. The outer part 49 comes to wrap the inner part 47 to protect it including shocks. The outer part 49 thus marries the inner part 47 by the outside of the latter, and is for example overmolded, surinjected, or fitted on this frame. Thus, the outer part 49 has a shape close to that of the inner part 47.

The outer part 49 comprises, in the same way as for the inner part 47, an annular wall 65 coaxial with the main axis X1. The annular wall 65 extends parallel to and away from the main axis X1 so as to surround the latter at a distance. The annular wall 65 forms six planar portions 67, 69 distributed around the main axis X1 and each having a rectangular shape parallel or orthoradial to the main axis X1. The planar portions 67, 69 are connected to each other by a filleted portion 71 which is projecting, so as to form a continuous annular wall. The planar portions 67, 69 extend parallel to the flat portions 53, 55. The outer part 49 also comprises a lower ring 73 projecting from the annular wall 65 towards the inside of the latter, towards the main axis X1 . The annular wall 65 extends between a lower edge 75 and an upper edge 77. The lower ring 73 projects from the annular wall 65 from the lower edge 75 so as to define an opening centered on the axis X 1 by the intermediate of which the inner part 47 is visible.

The outer part 49 comprises, instead of crenellations, three peripheral windows 79, 81 and 83. The latter are through, and each formed in one of the flat portions 69, on a portion of the latter, from the edge lower 75. Thus, when the inner part 47 and the outer part 49 are assembled with each other, peripheral windows 79, 81 and 83 open at the crenellations 17, 19 and 21 respectively, and in particular edge to edge. Thus, when the casing 7 is assembled, it has slots 17, 19, 21 which open respectively at three of the six planar portions 67, 69, which form three lateral faces 69 of the casing 7. In particular, each slot 17, 19 and 21 is provided at the lower edge 75 of one of the side faces 69.

The housing 7 thus having a hollow shape, the main battery 5 is disposed inside the latter, and in particular of the inner part 47.

The lighting module 1 also preferably comprises a control circuit 85, for example a printed circuit, which is also arranged inside the housing 7, and to which the main battery 5 is connected, in order to supply power to the battery. Electrical power control circuit 85. Preferably, the control circuit 85 has a substantially flat shape and is arranged to be surrounded by the annular wall 51. The main battery 5 is arranged between the control circuit 85 and the annular wall 51.

The lighting stage 3 is designed to provide a bright light, to project the latter in the direction of the main axis X1 so as to illuminate an area of the space that is close to it and, in particular, any object that 'find it. For this, the lighting stage comprises a reflector 87. The reflector 87 has a generally flattened shape which is delimited by a peripheral edge 89 complementary to the annular wall 51, so that the reflector 87 can be mounted within the housing 7 near the upper edge 63 of the annular wall 51. The reflector 87 includes three reflection cups 91 which are distributed around the main axis X1 in a regular manner, and which are formed inside the peripheral edge 89. The cups reflection 91 have for example a parabolic shape capable of reflecting and projecting the light out of the housing 7, substantially parallel to the main axis X1, or so as to slightly diverge or converge relative thereto.

The lighting stage 3 also includes a diffusion window 93, which makes it possible to diffuse or diffract the light coming from the reflector 87. The diffraction window is preferably made of transparent polymer, for example polycarbonate. Preferably, a hexagonal pattern favorable to the good diffusion of light, and imparting an aesthetic appearance to the diffusion pane 93, is formed in the latter. The diffuser window 93 has a slightly convex general shape centered on the main axis X1, and delimited by a peripheral contour 95 complementary to the peripheral edge 89 of the reflector 87, that is to say having a hexagonal general shape whose vertices are rounded to also correspond to the shape of the annular wall 51 of the inner part 47. The diffusion window 93 is designed to be assembled with the reflector 87 so as to close the space formed in the reflective cups 91. The lighting stage 3 finally comprises three electroluminescent diodes 97 which are installed between the diffusion window 93 and the reflector 87, and in particular respectively within each of the reflection cups 91 and which are connected to the control circuit by conductors. not shown.

Instead of light-emitting diodes 97, any other conventional electric lighting means may be provided. Similarly, one can provide a reflector of different shape, and change the number of reflection cups, as well as the number of lighting means depending on the situation. The lighting stage 3 shown in FIGS. 1 to 3 is nevertheless preferred, insofar as it has a good ratio between the quantity of light generated and the energy consumed, especially insofar as the light-emitting diodes 97 are implemented. rather than conventional bulbs.

The lighting stage 3 is assembled on the housing 7 at the upper edge 63 of the annular wall 51. Preferably, it is the peripheral contour 95 which is in contact with the upper edge 63 over the entire periphery of the latter , so as to form a sealed assembly. The lighting stage 3 is electrically connected to the main battery 5, and / or the control circuit 85, so that it can be supplied with electrical energy by at least one of these. When it is mounted on the housing 7, the lighting stage 3 is traversed by the main axis X1 and forms the upper part of the lighting module 1. The primary termination 13, in turn, forms the lower part of the lighting module which is opposed to the lighting plate 3, and which is also traversed by the main axis X1. In particular, it is the housing 7 which forms the primary termination 13 in its lower part.

The slots 17, 19 and 21 form means for positioning the lighting module 1. In fact, they allow the positioning and locking of the latter around its main axis X1, in particular the locking of the rotation of the lighting module 1 around this axis, and its positioning relative to this axis. The lighting module 1 can therefore for example be positioned on an object which has a shape complementary to that of the primary termination 13, and which has in particular studs 23, 25 and 27 which fit into the slots 17, 19 and 21 respectively, as described below. It is understood that, as a variant, only one of the three slots 17, 19 and 21 could provide this positioning function around the main axis X1. In the same way, the flat portions 67, 69 form positioning means of the lighting module 1, and in particular means for anti-rotation and positioning of the latter around the main axis X1.

The housing 7 also comprises a primary face 99 which is formed by the bottom wall 59 and the lower crown 73, the primary face 99 also forming a positioning means, insofar as the lighting module 1 can be placed on a surface bearing on its primary face 99. Indeed, the primary face 99 is preferably substantially flat, so that the underside of the housing 7 forming the primary terminal 13 is itself substantially plane.

The lighting module 1 also comprises a permanent magnet 33 which forms a means for maintaining the lighting module 1 in axial position by magnetic attraction on a support which is able to be attracted magnetically by the permanent magnet 33, for example a support including a magnetic element, such as a steel piece or other magnet. It is understood that by "maintaining in axial position" that the permanent magnet 33 is designed, and arranged to exert a holding force of the lighting module 1 in the direction of the main axis X1. The permanent magnet 33 is integral with the housing 7 and is disposed at the primary face 99, that is to say at the primary terminal 13. Preferably, the permanent magnet 33 is of annular shape coaxial with the main axis X1 and is disposed on the surface of the housing 7, while being integrally connected thereto. The permanent magnet 33 thus prevents the lighting module 1 from being detached accidentally from its support and ensures its maintenance in the position which is imposed by the positioning means formed the crenellations 17, 19 and 21. The position of the lighting module 1 is nevertheless removable, and allows a user to easily and quickly detach the lighting module 1 from its support, if necessary, by tearing the magnetic attraction between the permanent magnet 33 and the support.

Furthermore, the lighting module 1 comprises a first receiver terminal 31 designed to receive electrical energy for the supply of the main battery 5. The permanent magnet 33 forms a second receiver terminal associated with the first receiver terminal 31 to receive the electrical energy for the main battery 5. The first receiver terminal 31 is of discoid shape coaxial with the main axis X1, or at least through it, and is disposed on the surface of the housing 7, on the primary face 99. The second receptor terminal 33 formed by the permanent magnet 33 is disposed around the first receptor terminal 31, coaxially with the latter. The first receiving terminal 31 and the second receiving terminal 33 form two electric poles which are designed to transmit electrical energy for the supply of the main battery 5, or for the supply of the control circuit 85, or the power supply of the power supply. 3. In all cases, the electrical energy received at the receiver terminals 31 and 33 is intended to supply the lighting stage 3. The first receiver terminal 31 and the second receiver terminal 33 are provided so as to be flush with the surface of the housing 7. However, it could be envisaged that these terminals 31 and 33 are slightly sunken into the surface of the housing 7, or on the contrary are slightly protruding. The first receiver terminal 31 and the second receiver terminal 33 are preferably made of an electrically conductive metallic material, and are respectively designed to be brought into contact with a corresponding first supply terminal 35 and a second supply terminal 37 described. in the following. Alternatively, the permanent magnet 33 and the receiver terminals can form two separate parts. Conversely, as an alternative, the first receiver terminal 31 may also form a complementary permanent magnet for holding in position. Alternatively to the implementation of a permanent magnet, it could be envisaged to implement a removable adhesion surface or a gripping surface, including loops and hooks as known under the trademark VELCRO.

According to another variant not shown, the first receiver terminal is disposed within one of the notches 19, 21, distinct from the notch 17 in which the port 9 is disposed. The second receiver terminal is disposed within the remaining notch. In this case, each receiver terminal is disposed on the recessed surface 1527.

Preferably, the control circuit 85 is designed to adjust the illumination intensity of the lighting stage 3 as a function of the presence or absence of an electrical power supply at the first receiver terminal 31 and the second receiving terminal 33.

The control circuit 85 thus forms a means for adjusting the illumination intensity of the lighting stage 3 which makes it possible to automatically adjust the illumination intensity: at a first value, for example 70 lumens, it is ie 70 cd.sr (Candela Steradian), when the receiving terminals 31, 33 are not supplied with electrical energy and - at a second value, for example 150 or 200 lumens, which is greater than the first value, when the receiver terminals 31 and 33 are supplied with electrical energy.

Alternatively, it can be expected that the control circuit 85 does not increase, or little, the lighting intensity of the lighting stage 3, the additional electrical energy input allowing in this case to recharge the battery main 5.

The lighting stage 3 is designed to evolve between several modes of operation, and in particular between an off mode in which it emits no light, and a lit mode in which it emits lighting light. The transition from the off mode to the on mode, or the opposite, is for example by exerting pressure on the lighting plate 3 itself, parallel to the main axis X1, towards the inside of the housing 7. A alternatively, a control button or a switch, not shown, is placed on the surface of the housing 7 to switch the lighting stage 3 from its off mode to its on mode and vice versa. Optionally, the lighting stage has an intermittent lighting mode in which it flashes at a predetermined frequency. Successive presses on the lighting stage 3, or on the switch not shown, then allow to switch from one mode to another. Preferably, the connection of the first receiver terminal 31 and the second receiver terminal 33 to a power source makes it possible to automatically switch the lighting stage 33 from its off mode to one of the other modes. Conversely, the disconnection of the power source can automatically turn off the lighting plate 3. These operating modes of the lighting stage 3 are programmed within the control circuit 85 and driven by this latest.

The control circuit 85 may also be provided with a signal reception means, not shown, which makes it possible to receive remotely signals emitted from a remote control or a smartphone ("smartphone") in order to control the signal. mode of operation of the lighting stage 3. The control circuit 85 may also be provided with a signal transmission means which makes it possible to transmit remotely to a display means, for example the above mentioned apparatus, information on the charge level of the main battery 5, the current operating mode of the lighting stage 3, or the presence of a possible failure of the lighting module 1.

According to an optional aspect of the invention, the lighting module 1 further comprises a port 9 which opens at the surface of the housing 7 within the crenel 7, in particular at the recessed surface 1527. Preferably, the port 9 is oriented in a radial direction relative to the main axis X1, and is electrically connected to the main battery 5 and / or the control circuit 85. The port 9 is for example formed by a mini-USB port or any other port said "Standard" adapted to receive a male plug, and allowing the passage of at least one electrical power to supply the lighting stage 3, the main battery 5 and / or the control circuit 85. It is thus possible to recharge the lighting module 1 via the port 9 independently of the receiver terminals 31 and 33. The port 9 may optionally be designed to allow data exchange with the control circuit 85 for the programming of the latter, or to extract information from the latter, for example relating to the operating mode of the lighting stage 3 or the state of the main battery 5.

The lighting module 1 is preferably waterproof and / or dustproof construction, the port 9 may be designed to be also sealed or closed by a plug.

Figures 4 and 5 show an expansion module 15 which is designed to form together with the lighting module 1 a lighting assembly, by positioning the lighting module 1 on the extension module 15 as illustrated in Figure 6.

The expansion module 15 comprises a main body 1501 which defines a positioning axis X15. The main body 1501 comprises a secondary end 39 traversed by the positioning axis X15 and an opposite primary end 113 which is also traversed by the positioning axis X15.

The main body 1501 also comprises a peripheral surface 1503 which interconnects the primary termination 113 and the secondary termination 39. The peripheral surface 1503 surrounds the positioning axis X15 and has a generally cylindrical shape, preferably hexagonal base to rounded vertices, just like the lighting module 1. In particular, the peripheral surface 1503 forms six lateral faces 1505, 1507 which are evenly distributed around the positioning axis X15 each of the lateral faces 1505, 1507 connect the termination secondary 39 at the primary termination 113. The side faces 1505, 1507 each having a rectangular shape parallel or orthoradial to the axis X15. The side faces 1505, 1507 are connected to each other a portion fillet 1509 which is projecting, so as to form a continuous annular wall. The peripheral surface 1503 extends between a lower edge 1515 and an upper edge 1517. Preferably, as in the case of the lighting module 1, the extension module 15 comprises a housing formed by a hollow interior and a outer part overinjected or overmolded on the latter.

The secondary termination 39 has a shape complementary to that of the primary termination 13 to allow the positioning of the lighting module 1 on the extension module 15 by complementarity of shapes of the primary 13 and secondary 39 terminations. 1 can thus be assembled with the extension module 15 so that the primary face 99 rests on or is located parallel to a short distance from the secondary face 1513. In practice, the lighting module 1 is placed in position on the extension module so that the main axis X1 is coaxial with the positioning axis X15. In this situation, the lighting module 1 is in abutment with the extension module 15 in the direction of its main axis X1, and is rotated about this axis with respect to the extension module 15.

The primary 13 and secondary 39 terminations form a sliding connection along the positioning axis X15, and anti-rotation about this axis, the sliding of the lighting module 1 being limited along the axis of placing in position X15 to a final stop position of the primary termination 13 against the secondary termination 39, in which the lighting module 1 is in position on the extension module 15, as illustrated in FIG. 6. In this final position, the annular wall 65 and the peripheral surface 1503 are in continuity with each other, so that the lighting assembly has a generally cylindrical hexagonal shape coaxial with the axes X1 and X15.

As illustrated in FIG. 4, the secondary termination 39 comprises three tenons 23, 25 and 27 whose shape is complementary respectively to each of the slots 17, 19 and 21, so that the lighting module 1 can be placed in position on the extension module 15 by respective complementarity of the crenellations 17, 19 and 21 with the tenons 23, 25 and 27. In this case, the tenons 23, 25 and 27 project from the secondary face 1513, from the upper edge 1517, so as to each extend one of the three lateral faces 1507. The tenons 23, 25 and 27 extend parallel to the positioning axis X15, and are evenly distributed around the latter. Each tenon 23, 25 and 27 forms an ear or a tab which is intended to be inserted into one of the slots 17, 19 and 21. In practice, each tenon 23, 25 and 27 has a generally rectangular shape, and is delimited laterally by two secondary anti-rotation edges 1525, interconnected by a secondary abutment edge 1521 forming the top of the tenon concerned.

When the illumination module 1 is in position on the expansion module 15, the primary abutment edge 1519 comes into contact against the secondary abutment ridge 1521, for each of the three crenellations 17, 19 and 21 and tenons 23, 25 and 27, so as to jointly form a stop in translation along the positioning axis X15 of the lighting module 1 relative to the extension module 15. Moreover, the lighting module 1 is in position on the expansion module 15, the primary anti-rotation edges 1523 abut against the secondary anti-rotation edges 1525 so as to prevent the rotation of the lighting module 1 with respect to the extension module 15 around of the positioning axis X15. The primary 1523 and secondary 1525 anti-rotation edges also form the guide surfaces for the sliding of the lighting module 1 with respect to the extension module 15 along the positioning axis X15, and make it possible to ensure that the main axis X1 is coaxial with the positioning axis X15 when the lighting module 1 is placed in position on the extension module 15. As can be seen in FIGS. 1 to 5, the stop edges primary 1519 and secondary 1521, as well as the primary anti-rotation edges 1523 and 1525 secondary form in practice beveled surface elements that can improve reliability positioning of the lighting module 1 on the expansion module 15.

The tenons 23, 25 and 27 each comprise an inner surface 1529 turned towards the axis in position X15 and which extends parallel to the side face 1507 that extends the pin concerned. When the lighting module 1 is in position on the extension module 15, the recessed area 1527 of each slot 17, 19 and 21 is in contact with the inner surface 1529 of each of the tenons 23, 25 and 27, which makes it possible to ensure that the lighting module 1 is positioned on the extension module 15 so that its main axis X1 is coaxial with the positioning axis X15. Furthermore, in this positioning configuration, the port 9 is covered by the pin 23, so that it is protected from undesirable elements, in particular, dust, and preferably sealed by the pin 23. As a alternatively, the lighting module 1 may comprise a smaller number of slots, for example one or two, or a greater number of slots, for example five, and the extension module 15 a number of tenons corresponding to the number of slots. whatever it is, since the tenons and the slots are distributed spatially so as to allow the positioning of the lighting module 1 on the extension module 15.

As can be seen in FIGS. 4 and 5, the extension module 15 comprises a first power supply terminal 35 and a second power supply terminal 37 disposed on the surface of the main body 1501, and which makes it possible to supply the module with electrical energy. illumination 1 through the receiver terminals 31 and 33. The shape and arrangement of the power supply terminals 35 and 37 are provided for the latter to come into contact with the receiver terminals 31 and 33 when the lighting module 1 is in position on the extension module 15. As illustrated in the figures, the first power supply terminal 35 is discoidal coaxial with the positioning axis X15, or is at least traversed by the latter, and is located on the surface of the main body 1501, on the secondary face 1513. The second power supply terminal 37 has an annular shape and is arranged around the first power supply terminal 35, so that coaxial to the latter.

According to a variant not illustrated, in the case where the receiver terminals are disposed within the slots 19 and 21, the first power supply terminal can be disposed on one of the tenons 25 and 27, the second power supply being then disposed on another one of the studs 25 and 27. In particular, in this case, each power supply terminal is disposed on the inner surface 1529, in order to be able to come into contact with the receptor terminals which are themselves arranged on the surface. withdrawal 1527 when the lighting module 1 is in position on the extension module 15.

To supply energy to the power supply terminals 35 and 37, the expansion module 15 comprises an additional battery, not shown, which is enclosed in the main body 1501, which forms a hollow housing, so that the additional battery can power the main battery 5 via the power supply terminals 35 and 37 when the lighting module 1 is in position on the extension module 15, the supply terminals 35, 37 then being in contact with the receiving terminals 31.33. It can also be envisaged that the expansion module 15 is devoid of additional battery. In this case, it comprises, for example, a port 9 for supplying the power supply terminals 35, 37 with a source of external electrical energy. The port 9 of the extension module 15 is for example of the same type as the port 9 of the lighting module 1. The extension module 15 may have both a port 9 and an additional battery. Preferably, the additional battery has a capacity greater than the main battery 5. Thus, the extension module 15 allows the user, when he wishes, to extend the duration of illumination of the lighting module 1 , by forming a lighting assembly assembly of the lighting modules 1 and the expansion module 15, to the detriment of the overall size of the object and its weight. It will be understood that the lighting assembly is thus a modular system in which the user can assemble or dissociate as he pleases the lighting module 1 with the extension module 15 as a function of the situation with which he is confronted.

In addition, the permanent magnet 33 makes it possible to maintain the illumination modules 1 in axial position on the extension module 15, by magnetically attracting it to the second power supply terminal 37. It is also possible for the terminal of FIG. Power supply 37 itself forms a permanent magnet of reversed polarity with respect to that of the permanent magnet 33. Alternatively, it can be provided that the expansion module 15 comprises a metal body which is included in the main body 1501 and which is intended to be attracted by the permanent magnet 33. In any case, the permanent magnet 33 can plate, by magnetic attraction, the lighting module 1 against the extension module 15 in translation along the X15 positioning axis, which keeps in position the lighting module 1 on the expansion module 15. Thus, when the lighting module 1 is in position on the expansion module 15, which is autom In this case, the mounting and dismounting of the lighting module 1 on the extension module 15 is particularly easy and fast.

As can be seen in FIGS. 4 and 5, the extension module 15 comprises a primary termination 113 which is similar, preferably identical to the primary termination 13 of the lighting module 1. The primary termination 113 thus comprises three slots 117, 119 and 121 of positioning of the extension module 15, which are regularly arranged around the positioning axis X15, and have a similar shape, preferably identical to that of slots 17, 19 and 21 of the module In general, the primary termination 113 has a shape complementary to that of the secondary termination 39, so that two extension modules 15 can be connected to each other via their respective terminals. secondary termination 39 and their respective primary termination 113. In particular, the slots 117, 119 and 121 of the extension module 15 have a shape complementary to the pins 23, 25 and 27. Thus, it is possible to form a lighting assembly comprising the lighting module 1 and two modules of extension 15, and wherein the lighting module 1 is placed in position on a first of the two extension modules 15, the latter being itself placed in position on the second of the two extension modules 15. The termination primary 113 is disposed opposite the secondary termination 39 and is traversed by the positioning axis X15. The primary termination 113 is formed in the main body 1501. Opposite the secondary termination 39 and parallel thereto. It is understood that the lighting assembly forms a modular system.

The primary termination 113 also comprises a means for holding in position 33 the extension module 15, formed in this case by a permanent magnet 133 similar to the permanent magnet 33. In this case, the permanent magnet 133 is arranged at the surface of the primary termination 113 and has an annular shape which is coaxial with the positioning axis X15. The primary termination 113 also includes a first receiver terminal 131, the magnet 133 forming a second receiver terminal 133. The receiver terminals 131 and 133 are similar, preferably identical, to the receiver terminals 31 and 33. The receiver terminals 131 and 133 are designed to receive electrical power for powering the power terminals 35 and 37 or in particular the additional battery mentioned above.

FIGS. 7 and 8 show a second embodiment of the extension module 15, itself shown in FIGS. 4, 5 and 6, which is referenced 115. In these FIGS. identical elements that correspond to those of Figures 4 to 6 and described in the foregoing. This is also the case for the other embodiments described in the following.

The extension module 115 thus comprises a main body 1501 with a positioning axis X15, a secondary termination 39 with tenons 23, 25 and 27, the secondary termination 39 having a shape complementary to that of the terminal 13 of the module 1 and the primary termination 113 of the extension module 15, - a first power supply terminal 35 and a second power supply terminal 37 arranged at the secondary termination 39, - an additional battery, not shown, enclosed in the main body 1501, a primary termination 113 formed opposite the secondary termination 39 and traversed by the positioning axis X15, and whose shape is complementary to that of the secondary terminations described above.

In this second embodiment, the main body 1501 has a substantially cylindrical elongate shape about the positional axis X15, so as to connect the primary termination 113 to the secondary termination 39. As in the case of the embodiment illustrated in FIGS. 4 to 6, the main body 1501 of the extension module 115 comprises six lateral faces 1505 and 1507 as well as portions in fillet 1509. Nevertheless, in the case of this second embodiment, the peripheral surface 1503 also comprises a gripping zone 1531 which extends over a fraction of its length. The gripping zone 1531 is, in practice, formed by three handle surfaces 1535, which themselves form longitudinal flats formed in the peripheral surface 1503, and distributed around the positioning axis X15. Each of the handle surfaces 1535 forms a recess in one of the lateral faces 1507, and extends parallel to the lateral face 1507 concerned, recessed towards the inside of the main body 1501. As shown in FIGS. 8, the handle surfaces 1535 are advantageously provided with non-slip reliefs to allow gripping of the extension module 115 by the hand of a user. Thus, the handle surfaces 1535 may have a plurality of grooves or printed braces during manufacture of the piece, giving slip resistance.

Since the extension module 115 has a longer length, along the positioning axis X15, than that of the extension module 15, it is possible to provide an additional battery of greater size therein. Consequently, placing a lighting module 1 on the extension module 115 makes it possible to form a lighting assembly whose lighting autonomy is particularly high. Moreover, the extension module 115 can be put in position, via its primary termination 113, on an extension module 15, via the secondary termination 39 of the latter, in order to further extend the autonomy. of the lighting assembly thus formed. This lighting assembly which comprises at least the lighting module 1 and the extension module 115 advantageously forms a modular flashlight. Thus, according to the assembly combinations of the lighting module 1, the extension module 15 and the extension module 115 made by the user, the latter can obtain a lighting assembly adapted to the situation in which he is located.

As described below, the lighting assembly may also include a plurality of lighting modules 1 according to those of FIGS. 1 to 6.

Figures 9 to 11 show a lighting assembly including a plurality of lighting modules 1, and an expansion module 215. The latter is a third embodiment of the expansion module.

The extension module 215 comprises a trunk 2101 which defines a trunk axis X215, and which comprises three branches 2102 which project radially relative to the trunk axis X215 outwardly. The branches 2102 are attached to the trunk 2101 by a first end of the latter, the trunk 2101 ending at an opposite second end forming a primary termination 113 in accordance with what has been previously described for the extension module 115. The primary termination 113 is traversed axially by the trunk axis X215. The branches 2102 each end at their radial end by a pivot link 2105 having a pivot axis X 2105. The pivot axes 2105 are oriented ortho-radial with respect to the trunk axis X215. The expansion module 215 also comprises three mobile pedestals 2103 which are mounted on the branches 2102 via the pivot links 2105 so as to be pivotable respectively about their pivot axis X2105. Each mobile base 2103 comprises two support wings 2106 disposed on either side of the pivot connection 2105 and extending in a direction parallel to the pivot axis X2105. The support wings 2106 form a second embodiment of the secondary termination 39. Indeed, each support wing 2106 is provided to receive a lighting module 1 shown in Figures 1 to 3. Indeed, each support wing 2106 defines a positioning axis X2106. Each support wing 2116 comprises a positioning flange 2109, which is of complementary shape with the annular wall 65, and in particular with the six flat portions 67 and 69 of the lighting module 1. In this case, the flange 2109 is of hexagonal shape, and is intended to surround the annular wall 65 so that the lighting module 1 can slide within the implementation flange along the positioning axis X2106 which is then coaxial with its main axis X1. The prismatic arrangement of the planar portions 67 and 69 makes it possible to block the rotation around the positioning axis X2106 of the lighting module 1 with respect to the support wing 2106 concerned. The support wings 2106 also each comprise a bottom wall 2111 from which the flange 2109 projects, the bottom wall 2111 extending substantially in a plane orthogonal to the positioning axis X2106 so as to form a flange. axial stop of the primary termination 13 of the lighting module 1. Thus, the lighting means 1 is set in position in the support wing 2106 while it is locked in rotation about the pivot axis 2105 by the flange 2109, and that it abuts against the bottom wall 2111 in particular via its primary face 99. The flange 2109 and the bottom wall 2111 together form a cup for positioning the module 1. The support wings 2106 are provided with power supply terminals, not shown, with lighting modules 1, these power supply terminals being arranged on the surface of the bottom wall 2111 coaxially with the axis of application. posi X2106. These supply terminals may, in particular be of the same type as the terminals 35 and 37 mentioned above. Thus, when the lighting modules 1 are placed in position on the support wings 2106, their receptor terminals 31, 33 are in contact with these supply terminals. Furthermore, as described above, the second receiving terminal 33 forms a permanent magnet capable of holding the lighting module 1 in position on the support wing 2106 by magnetic attraction of the latter.

As can be seen in FIGS. 10 and 11, the mobile pedestals 2103 are rotatably mounted around the pivot axes X2105. Thus, the mobile pedestals 2103, and therefore the support wings 2106, can be oriented around the pivot axes X2105 relative to the trunk 2101. The user can thus orient the pairs of illumination module 1 around these pivot axes X2105 to adjust the area lit by them.

The extension module 215 also comprises a central button 2113 which makes it possible to control the supply of electrical energy to all the lighting modules 1 in position on the extension module 215, and thus to control at the same time the transition to mode off and in the on mode of all these lighting modules 1.

It is understood that the extension module 215 can itself be placed in position on another extension module 15 or 115 via its primary termination 113. The electrical power supply of the lighting modules 1 in position on the extension module 215 may thus be provided by the extension module 15 or 115 on which it is placed in position, and / or by an additional battery included for example in the trunk 2101. The set of lighting of Figures 9 to 11 thus forms a modular lighting spot, with several lighting modules 1 whose light is combined.

The extension module 215 may comprise a lower or upper number of branches 2102, for example two branches 2102 or six branches 2102 distributed around the trunk axis X15. Similarly, the mobile pedestals 2103 may comprise a single support wing 2106 or on the contrary a number greater than two support wings 2106. The mobile pedestals 2103 may comprise a plurality of secondary terminations 39 as described in the foregoing, alternatively to support wings 2106.

FIGS. 12 and 13 illustrate a fourth embodiment of the extension module, which is numbered 315. The extension module 315 comprises a secondary termination 39 and a primary termination 113. It forms a base on which is intended to be placed. in position the lighting module 1 of Figures 1 to 3, or an extension module 15, 115 or 215, as shown in Figure 13. The primary termination 113 of the expansion module 315 is designed to be positioning in another expansion module 15 or 115 for its power supply. Alternatively, as shown in FIG. 13, the primary termination 113 of the extension module 215 may be connected to, i.e., turned on, a power cord 3101 terminated secondary 39 adapted. This power cord 3101 makes it possible to supply the extension module 315, the expansion module 215, and the lighting modules 1 mounted with the extension module 215 with electrical energy.

The extension module 315 may be provided with an additional internal battery for supplying electrical energy to its secondary termination 39.

Expansion module 315 includes, like expansion module 15, a main body 1501 with a peripheral surface 1503 including secondary termination 39 and the aforementioned primary termination 113. Additionally, the expansion module 315 comprises a support structure 3103 which is formed by an assembly of tubular elements, including: two radial arms 3105 which project from the main body 1501 in a substantially radial direction relative to the X15 positioning axis defined by the latter; two transverse arms 3107 which are each connected to one of the two radial arms 3105, at a median portion of each transverse arm 3107, so that each transverse arm 3107 forms with its associated radial arm 3105 a " T "; two bent arms 3109 each connecting the transverse arms 3107 to each other while being connected to the end thereof.

The two bent arms 3109 have a shape of "V" and extend perpendicularly to the transverse arms 3107, so that the bend formed by each of the bent arms 3109 is directed substantially in the same direction as the primary termination 113.

According to this configuration, the extension module 315 forms a base designed to rest for example on the ground, resting on the bent arms 3109 and on one of the two transverse arms 3107. The lighting assembly formed by at least a lighting module 1 and the extension module 315, and optionally including the extension module 215 as shown in Figure 13, thus form a lamp adapted to rest on the ground and to be powered by the cord of 3101. It is understood that the modular nature of the lighting assembly makes the latter particularly versatile.

FIG. 14 illustrates another embodiment of the lighting assembly described above comprising a fifth embodiment of the extension module 15, 115, 215 and 315 described above, which is numbered 415.

Like the expansion modules 15 and 315, the extension module 415 comprises a main body 1501 with a positioning axis X15, a secondary termination 39 and a primary termination 113 opposite the secondary termination 39. As in FIG. In the case of FIG. 13, the extension module 215 is placed in position on the secondary termination 39 of the extension module 415. On this extension module 215, six lighting modules 1 in accordance with FIG. The expansion module 415 is integrated with a conventional tripod 4000. Thus, the extension module 415 forms a support which can be placed on the ground via the tripod 4000, in a manner comparable to the module of extension 315.

Fig. 15 illustrates a sixth embodiment of the extension modules described in the foregoing, which is numbered 515.

The expansion module 515 includes a ring-shaped harness 5101, which is designed to be mounted on the head of the user or for example to the size of the latter. The expansion module 515 also includes a secondary termination 39 mounted on the harness 5101 and as described above. The secondary termination 39 can thus receive the lighting module 1 described above. The expansion module 515 also includes a primary termination 113, mounted on the harness 5101 opposite the secondary termination 39. It is understood that the primary termination 113 allows to receive the extension module 15 described above. The power terminals of the secondary termination 39 are electrically connected to the receiving terminals of the primary termination 113 via a connection not shown, formed within the harness 5101. It is thus understood that it is possible to supply the lighting module 1 placed in position on the secondary terminal 39 of the extension module 515 by means of the extension module 15 which is mounted on the primary terminal 113 of the extension module 515. The extension module 515 and the lighting module 1 thus form a lighting assembly, optionally provided with the extension module 15. This particular lighting assembly forms a modular headlamp.

FIG. 16 represents a seventh embodiment of the extension module described above, numbered 615.

The expansion module 615 comprises a winding drum 6101 and a power cord 6103 wound therein. The take-up drum 6101 has a side face 6105 which is provided with four secondary terminations 39 and three power outlets 6107. The latter are supplied with electricity by the power cord 6103, which can change, thanks to the winding drum 6101, between a wound configuration within the drum reel 6101, and an unwound configuration of the drum reel 6101. The power outlets 6107 can receive the electrical plugs 6109, for the electrical power supply of the latter. In the same way, lighting modules 1 can be placed in position on the secondary terminations 39 in order to be supplied with electrical energy, via these latter, by the power cord 6105.

Figures 17 and 18 show a second embodiment of the lighting module 1 of Figures 1 to 3, numbered 101. The lighting module 101 comprises a housing 107 defining a main axis X1, the lighting plate 3, the main battery which is not shown, and which is arranged inside the housing 107 to supply the lighting stage 3 with electrical energy. The housing 107 is provided with the primary termination 13 already described, and traversed by the main axis X1. The primary termination 13 is disposed opposite the lighting stage 3, and comprises the three notches 17, 19 and 21 as well as the receiving terminals 31 and 33, the second receiving terminal 33 being a permanent magnet forming a means of holding in position the lighting module 101.

The lighting module 101 differs from the lighting module 1 in that the housing 107 has a shape different from that of the housing 7 with two portions whose dimensions perpendicular to the axis X1 are different. The casing 107, however, will have the same constitutional elements as the casing 7, and in particular: the inner part, not shown, and the outer part 149, which is of different shape than the part 49, but which is advantageously made in the same subject, and has the same functions.

In particular, the outer part 149 comprises the peripheral windows 79, 81 and 83 described above. The outer part 149 also forms the primary face 99 of the primary termination 13. The outer part 149 connects the primary termination 13 to the lighting stage 3 and forms an annular wall 165 comparable to the annular wall 65, and which extends all around the main axis X1. The annular wall 165 comprises a first portion 210 which extends from the plate 3 towards the primary end 13, and which is substantially cylindrical, hexagonal base whose peaks are rounded. The annular wall 165 also comprises a second portion 230 which extends from the first portion 210 towards the primary termination 13. The second portion 230 is of generally annular shape and converges towards the main axis X1 from the first part 210. The annular wall 165 also comprises a third portion which forms the primary termination 13, and which is generally cylindrical in shape, hexagonal base with rounded vertices. According to this configuration, because of the presence of the second part 230, the lighting plate 3 has, in consideration of the main axis X1, a larger diameter than the primary termination 13, that is to say that the primary face 99. The first portion 210, the second portion 230 advantageously form a cap, so that the annular wall 165 forms an overhang.

It is understood that the lighting stage 3 of the lighting module 101 being larger in size than the lighting stage 3 of the lighting module 1, it can therefore be of higher power.

FIG. 19 illustrates a lighting module 201 according to a third embodiment of the invention, and similar to the lighting module 1, with the difference that it comprises a primary termination 213 instead of the primary termination 13 previously described. The characteristics of the lighting module 201 which correspond to the characteristics of the lighting module 1 have been indicated by the same reference signs increased by 200.

The lighting module 201 comprises a lighting stage 203 and a main battery identical to those of the lighting module 1. The lighting module 201 also comprises a housing 207 and a primary terminal 213. The height H201 of the module 201 lighting is identical to the height H1 of the lighting module 1.

The housing 207 defines a main axis X201 corresponding to the axis X1 described above.

For convenience, the rest of the description is oriented relative to the axis X201, considering that the terms "upper" and "top" correspond to an axial direction facing the upper part of FIG. 19, while the The terms "lower" and "lower" correspond to an axial direction of opposite direction.

The housing 207 comprises, like the housing 7, an inner part 247 or armature which is preferably made of a rigid plastic material of the polypropylene type. The inner part 247 is only partially visible in Figure 19. It is, in this case, hidden and wrapped by an outer part 249 described below. The inner part 247 and is substantially identical to the inner part 47 of the housing 7.

The inner part 247 comprises a bottom wall 259, which extends orthogonal to the axis X201, so as to close the annular wall of the inner part 247 from the lower edge thereof, opposite the upper edge supporting the plate 203. The inner part 247 differs from the inner part 47 of the housing 1 in that it does not present the slots 17, 19 and 21 of the first embodiment.

The housing 207 is provided with a fixing ring 248 which protrudes from the bottom wall 259 to the module 201, coaxially with the axis X201, along this axis. The ring 248 is provided with three internal ribs 250 protruding directed towards the inside of the ring 248 and distributed around the axis X201. Each of the ribs 250 extends over only a portion of an inner contour 252 of the crown 248, so that the ribs 250 are separated by three empty spaces 254. Each of the ribs 250 defines two ends 256 and forms an arc delimited by these two ends 256. Each of the ribs 250 extends remotely and overhanging the bottom wall 259 and defines an inner surface 258, directed towards the bottom wall 259, opposite and at a distance from the latter.

The outer part 249 surrounds the inner part 247 in its shape, in order to protect it from shocks, so that the shape of the hidden elements of the inner part 247 can be guessed by observing the outer part 249.

The outer part 249 thus comprises an annular wall 265, with six flat portions 267, 269 connected to each other by projecting portions 271 protruding. The outer part 249 also comprises a lower ring 273 similar to the lower ring 73 of the lighting module 1 defining an opening centered on the axis X201 and through which the inner part 247 is visible in FIG. Annular wall 265 includes a lower edge 275 and an upper edge 277.

In the absence of slots, the outer part 249 is advantageously devoid of windows, unlike the outer part 49 of the module 1. The bottom wall 259 and the lower ring 273 form a primary face 299. Alternatively, the parts 247 and 249 may form only one part. In any case, the housing 207 has a hollow shape, the main battery, not shown, being disposed inside the latter, and in particular inside the inner part 247, similarly to the module 1 .

The lighting module 201 comprises, like the module 1, a control circuit to which the main battery is connected.

Furthermore, the lighting module 201 comprises receiving terminals 231 and 233 similar to the receiving terminals 31 and 33 of the module 1. The first receiving terminal 231 is discoidal coaxial with the main axis X201, or is at least traversed by the latter. It is disposed on the surface of the housing 207, on the primary face 299, in particular on the bottom wall 259. The second receptacle terminal 233 is disposed around the first receptacle terminal 231, coaxially with the latter. The bottom wall 259 forms a local boss 260, forming a dome centered on the axis X201, the terminals 231 and 233 being disposed at the surface of this local boss 260, at the top of the latter.

The terminals 231 and 233 as well as the ribs 250 form the primary termination 213 of the module 201 at the bottom wall 259. The primary termination 213 thus forms a lower portion of the lighting module 201 which is opposed to the plate of lighting 203 and which is crossed by the main axis X201. In particular, it is the housing 207 which forms the primary termination 213 in its lower part.

The fixing ring 248 and the ribs 250 form means for positioning the module 201 along and around the axis X201, on a secondary end 239 of complementary shape, described below. The ends 256 of the ribs 250 form in particular anti-rotation stops of the module 201 around the axis X201.

The ribs 250 furthermore form means for holding the lighting module 201 in position along the axis X201, insofar as complementary external ribs 264, described hereinafter, can be interposed between the bottom surface 259. and the inner surface 258 to retain the module 201 along its axis X201.

FIG. 20 illustrates an extension module 715 according to an eighth embodiment according to the invention. The expansion module 715 is comparable to the extension module 15 of FIGS. 4 and 5, but comprises in particular a secondary termination 239 different from the secondary termination 39 of the module 15. This secondary termination 239, as described below, is particularly adapted to be associated with the primary termination 213 of the module 201 of Figure 19, to form a lighting assembly comprising the lighting module 201 and the expansion module 715.

Expansion module 715 includes a main body 1501 which defines a positional axis X15. The secondary termination 239 is traversed by the positioning axis X15 and an opposite primary termination 1213, similar to the primary termination 213 of the embodiment of FIG. 19, the primary termination 1213 also being traversed by the placing axis. in position X15.

The main body 1501 also comprises a peripheral surface 1503 which interconnects the primary terminal 1213 and the secondary terminal 239. The peripheral surface 1503 surrounds the positioning axis X15 and has a generally cylindrical shape, the entire extension module 15. In particular, the peripheral surface 1503 forms six lateral faces 1505, 1507 which are regularly distributed around the positioning axis X15, each of the lateral faces 1505, 1507 connecting the secondary termination 239 to the primary termination 1213. The faces 1505, 1507 are connected to each other by a fillet portion 1509. The peripheral surface 1503 extends between a lower edge 1515 and an upper edge 1517.

The secondary termination 239 has a shape complementary to that of the primary termination 213 to allow positioning and holding in position of the lighting module 201 on the extension module 715 by complementarity of forms of the terminations 213 and 239.

In particular, the secondary termination 239 includes a secondary face 1513 which extends in a substantially orthogonal plane with respect to the axis X15 and closes the edge 1517. The termination 239 also comprises a centering crown 262 projecting from the face 1513 coaxially with the axis X15. The centering ring 262 has a diameter that allows it to be housed inside the fixing ring 248, coaxially with the latter, so that the module 201 can be positioned on the module 715 by insertion of the crown 262 in crown 248.

The secondary termination 239 further comprises three outer ribs 264 which protrude centrally from the ring 262, away from the face 1513 and radially with respect to the axis X15. Each of the outer ribs 264 extends over only a portion of the circumference of the ring 262 and is delimited by an insertion end 266 and a stop end 268. The insertion and stop ends 266 are arranged alternately. around the axis X15, so that the ribs 264 are oriented in the same orthoradial direction. Three axial insertion axial spaces 270 of the three internal ribs 250 are each formed between two external ribs 264, the angular sector, with respect to the axis X15, separating the end 266 from a first one of the outer ribs 264 and the outer rib 264. end 268 of a second of the outer ribs 264 being greater than or equal to the angular sector, with respect to the axis X201, occupied by each of the internal ribs 250. Conversely, the angular sector, with respect to the axis X201, defined by each of the empty spaces 254 is greater than or equal to the angular sector, with respect to the axis X15, of the external ribs 264, so as to allow axial insertion of the ribs 264 between the ribs 250.

Each rib 264 defines an inner surface 272 directed toward the face 1513. The surface 272 is intended to come into contact with the inner surface 258 of the ribs 250. In particular, the axial distance between the surface 272 and the face 1513 is greater or equal to the axial thickness of the ribs 250. Similarly, the axial distance between the surface 258 and the bottom wall 259 is greater than the axial thickness of the ribs 264.

Furthermore, the secondary termination 239 comprises three abutment ribs 274. Each of them connects the surface 272 of one of the ribs 264 to the face 1513 on only a portion of the angular sector occupied by the rib 264 concerned, from from the end 268 of the latter. Three anti-rotation stops 276 are thus formed, each by one of the ribs 274. Each stop 276 thus extends between one of the surfaces 272 and the face 1513, so as to be able to block the rotation of the module 201 relative to to the module 715 about the axis X15, by abutting the ribs 250 against the stops 276. Opposite their abutment 276, each rib 274 defines an insertion slope 278, which extends the end 266 in the direction of the face 1513.

The lighting module 201 can thus be assembled with the extension module 715 according to the following steps: coaxial translation of the module 201 in the direction of the module 715, the primary termination 213 being directed towards the secondary termination 239, the modules 201 and 715 being oriented relative to each other about the axis X15 so that the ribs 250 are inserted between the ribs 264, - rotating the module 201 relative to the module 715 about the axis X15, advantageously by guiding the ribs 250 against the insertion slopes 278, so that each rib 250 is admitted between one of the ribs 264 and the face 1513, the rotation being continued until the end 256 of each side 250 arrives in a final stop position against one of the abutments 276. In this example, a third of a turn around X15 allows this abutment.

In this final stop position, the module 201 is placed in position on the module 715 both around the axis X15 by abutting the ribs 250 against the stops 276 and along the axis X15 by abutting internal surfaces 272 and 258 against each other. The abutment of the inner surfaces 272 and 258 against each other also keeps the module 201 in axial position relative to the module 715. In this final stop position, the annular wall 265 and the peripheral surface 1503 are in the continuity of one another, so that the lighting assembly has a generally cylindrical hexagonal base coaxial with axes X201 and X15.

The lighting module 201 can thus be assembled with the extension module 715 so that the primary face 299 rests on or is located parallel to a short distance from the face 1513 of the module 715. The assembly of the primary terminations 213 and secondary 239 is particularly strong and reliable, due to the arrangement and shape of the three ribs 250 and three ribs 264. The primary termination 213 comprises at least three ribs 250, and the secondary ending 239 at least three ribs 264, for guarantee the reliability of the assembly. Alternatively, the number of ribs 250 and 264 can be changed. Similarly, the terminations 213 and 239 may be inverted, that is, the characteristics described above for the termination 239 are applied to the termination 213 and the characteristics described above for the termination 213 are applied. at the end 239.

The extension module 715 comprises a first power supply terminal 35 and a second power supply terminal 237 disposed on the surface of the main body 1501, and which makes it possible to supply electrical power to the lighting module 201 via the terminals Receivers 231 and 233. The shape and arrangement of the power supply terminals 35 and 237 are provided for the latter to come into contact with the receiver terminals 231 and 233 when the lighting module 1 is in the final stop position on the module. 715. In this case, the local boss 260 is sufficiently protruding to place the terminals 231 and 233 at the height of the secondary face 1513.

As illustrated in the figures, the first power supply terminal 35 is of discoid shape coaxial with, or at least traversed by, the positioning axis X15, and is disposed on the surface of the main body 1501, on the face secondary 1513. The second power supply terminal 237 has a shape similar to the terminal 35 and is disposed at a radial distance from the first terminal 35 which is equal to the radius of the terminal 233. The terminals 35, 237 come into contact with the receiving terminals 231, 233 when the module 201 is positioned on the module 715 through their respective terminations 213 and 239. To power the power supply terminals 35 and 237, the expansion module 715 includes an additional battery, not shown, which is enclosed in the main body 1501.

The elements common between these two lighting modules 201 and 401 are indicated by common reference signs.

The lighting module 401 differs from the module 201 in that it does not include the receiving terminals 231 and 233, but instead comprises receiving terminals 331, 332 and 333. The bottom wall 259 is devoid of any projection. local and is substantially flat, unlike the lighting module 201 of Figure 19.

Each of the three receiver terminals 331, 332 and 333 is of disc shape, and is positioned on the surface of the housing 207, on the primary face 299 of the latter and in particular on the surface of the outer ring 273. The receiving terminals 331, 332 and 333 are therefore arranged away from the X201 axis. The receiver terminals 331, 332 and 333 are aligned and arranged on circles centered on the axis X201 and of different diameters.

A first receiving terminal is called "common terminal 331". A second receiving terminal is called "battery charging terminal 332", the power supply of the common terminal 331 and the battery charging terminal 332 for charging the internal battery of the module 401, these terminals 331 and 332 being electrically connected to the terminals of the battery, or the internal control circuit of the module 401. The third receiving terminal is said "lighting terminal 333", the power supply of the lighting terminal 333 and the common terminal 331 causing lighting of the lighting plate 203. For this, the terminals 331 and 333 are electrically connected to the lighting plate 203, or to the internal control circuit of the module 401.

It is understood that the function of each terminal 331, 332 and 333 is interchangeable.

The module 401 comprises a port 409, which is similar to the port 9 of the lighting module 1 illustrated in FIGS. 1 to 3, and which performs the same function as this port 9. The port 409 is disposed on the surface of one of the planar portions 267 or 269 and is electrically connected to the main battery and / or the control circuit and / or the lighting stage 203.

FIG. 24 illustrates an extension module 915 according to a tenth embodiment of the invention, and similar to the extension module 715 of FIG. 20. In what follows, only the differences between the extension module 915 of FIG. 24 and the module 715 of FIG. 20 are described, the other elements not described being common to these two extension modules 715 and 915. The elements common between these two these two extension modules 715 and 915 are indicated by common reference signs.

The expansion module 915 differs from the module 715 in that it comprises discoid-shaped power supply terminals 435 and 437, replacing the supply terminals 35 and 237, which are absent from the extension module 915. The power supply terminal 435 performs the same function as the power supply terminal 35 and the power supply terminal 437 performs the same function as the power supply terminal 237. The power supply terminals 435 and 437 are arranged on the surface of the face secondary 1517, radially relative to the axis X15, outside the ring 262. The supply terminals 435 and 437 are arranged on circles centered on the axis X201 and of different diameters. In general, the terminals 435 and 437 are arranged in such a way that when the lighting module 401 is mounted on the extension module 915 through, respectively, the primary termination 213 and the secondary termination 239 the terminals 435 and 437 are in electrical contact with the terminals 332 and 333, so as to supply the lighting module 401 with electrical energy so as to enable the module 401 to illuminate.

It will be understood that, when it comes to recharging the internal battery of the module 401, a charger equipped with supply terminals which interact with the terminals 331 and 332 is used.

As a variant, one of the ribs 250, called the "coding rib" occupies an angular sector, with respect to the axis X201, which is of different width from that of the other ribs 250. In other words, the rib of keying is longer or shorter than the other ribs 250. One of the circular spaces 270, called "circular polarization space" defines an angular sector, with respect to the axis X15, which is of different width from the others circular spaces, the width of this angular sector being adapted so that the keying coast can be inserted into the circular polarizing space. In other words, the circular keying space is longer or shorter than the other circular spaces 270, depending on the size of the keying coast. The polarizing coast and the circular polarizing space thus form keying means, which allow the assembly of the module 401 on the module 915 in a single relative orientation about the axis X15. Thanks to the keying means, the relative orientation of the modules 401 and 915 when they are assembled corresponds to the position in which the terminals 435 and 437 are connected with two of the terminals 331, 332 and 333. Other polarizing means may be implemented. work, for example visual.

The expansion module 915 comprises a port 909, which is similar to the port 9 of the lighting module 1 illustrated in FIGS. 1 to 3, and which performs the same function as this port 9.
